Utility-Scale Solar Calculator — Queensland

MWh/year estimate for a utility-scale plant in Queensland — specific yield, PR and monthly generation table.

Screening a solar farm site in Queensland? Enter plant capacity in kW (5,000 kW = 5 MW); the output table gives MWh-scale monthly generation from the regional resource. Queensland's sun rivals India's, and STC rebates still knock thousands off install cost — but many networks cap exports at 5 kW, so size for self-consumption. For bankable studies, replace the GHI default with on-site or satellite TMY data.

  • ✓Everything computes instantly in your browser — no signup, no quote-form ambush

Frequently asked questions

How accurate is the Utility-Scale Solar Calculator — Queensland?+

It uses the same physics as NREL's PVWatts: irradiance × plane-of-array factor × performance ratio. With honest inputs, expect results within ±10% of a professional simulation — good enough for sizing and payback decisions. For bankable projects, follow up with site-measured data and a full TMY simulation.

What is specific yield and what's a good value?+

Specific yield is annual kWh produced per kW of panels. It removes system size from the comparison: 1,400–1,700 kWh/kWp is typical across sunny India, 950–1,100 in Germany or the UK. If a quote promises far above the regional norm, question the assumptions.

Why is my real output lower than the calculator says?+

The usual suspects in order: more shading than assumed, dust (soiling can cost 5–15% where cleaning is irregular), inverter undersizing/clipping, and higher cell temperatures than the default loss stack assumes. Compare measured monthly output against the table here to localize the gap.

Does panel direction matter as much as size?+

Orientation typically moves output 5–25%. Equator-facing at near-latitude tilt is ideal; east/west roofs lose roughly 10–20% but spread generation across the day, which can be worth more under time-of-use tariffs or self-consumption rules.
